that mask looks like a welder's hood, but i know it isn't one. what the **** is it?

He made this video when I pissed him off one day. I think its the same weird skull mask he used in the water bottle video. It looks like some comic book villain mask. Is it venom?
The best part of the video is the knife strapped to his leg.

things heat up around 2.30, when he takes his kit off...a man after my own heart

He has a big hole in the crotch of his pants. When it shows you the close up of him doing low kicks you can tell. Couldnt he get black tactical ninja pants without a hole? Why did he film in those? He must have been to excited to be patient and get new pants.
